Application filed August 11, 1926, Serial This invention relates to an apparatus for nautical sports which is entirely insubmersible, and by its use all persons even though unable to swim, can bathe in the sea or rivers irrespectively of the depth of the bottom, and may travel at speeds attaining 15 kilometers an hour.

If necessary, the said apparatus maybe provided with a small internal combustlon engine or a compressed air motor.

The accompanying drawing, given as an example shows one of the forms in which this invention is carried out.

Fig. 1 is an elevational view of the apparatus.

Fig. 2 is the corresponding plan view.

The apparatus comprises a main beam consisting of aluminium and made in two parts A and B, the rear part B telescoping in the front part A, so that the length of the apparatus can be adjusted to the person employing the same.

The front part of themain beam A com prises a float consisting of copper or aluininium C which is divided into three watertight compartments by means of the cork walls U, the device being filled with kapok fibre V. V

To the rear part of the main beam B is secured a copper or aluminium float D which, in the same manner as the float C, is divided into watertight compartments by means of the cork walls U, with thekapok filling V. Below the front beam A is disposed a combined float and keel E which serves to prevent the apparatus from travelling towards the open sea during bad weather.

In the same manner as the floats C and D, the float E consists of watertight compartments formed by means of the cork walls U, the whole being filled with the kapok fibre The front beam A is provided with a. steering wheel F which controls two rods G and G actuating the rudder H.

A supporting arm I is engaged in a bracln. et J which is mounted on the front beam A, and the said arm is adjusted according to the height and the length of the arms of the user.

Below the main beam B is mounted the landing skid K. At the rear part of the beam B, and below the float D is mounted the mechanical power transmission device, comprising the aluminium casing Lconta1n- No. 128,657, and in France May 12, 192s.

ing the large bevel gear wheel M which is keyed to a shaft N upon which are mounted the pedalsO'and O. A pinion P provided with a shank, which is mounted in the thrust ball bearings Q, actuates the propeller R whereby the apparatus is caused to travel. The aluminium casing L is made watertight by the stuffing boxes S, S S.

The operation of the said apparatus is as follows:

The water level is shown by the line X-X, and the apparatus assumes the position shown in Fig. 1. The swimmers body is partly submerged, and he bears with his shoulders against the supports I and J and places his feet upon the pedals i0 and O, which are providedwith foot supports. He grasps the steering wheel F with the hands, and propels the pedals by a rotary motion with his feet.

The length of the apparatus can be adjusted in accordance with the persons body.

All the rotating parts are mounted by means of ball bearings, these being extended in the casing by stufling boxes.

The apparatusis made in two parts.

All of the said pieces are removable and interchangeable, so that they may be replaced and cleaned with facility.

Obviously, the said apparatus which is deseribedbyway of example is susceptible of r various modifications in its construction, as well as of various changes in the details.

On the other hand, for the. elements here in disclosed by way of example I may substitute other elements answering the same purpose.

I claim:

1. A swimming device. comprising an ad justable main beam watertight compartment positioned thereon, propelling means associated with said beam, a rudder attached to the rear of said beam, controlling mechanism for opera-tin said rudder and adj ustable arm supports mounted on said beam.

2. A swimming device comprising an adjustable main beam, a rudder secured to said beam, a rudder control mechanism for operating said rudder, propelling means associated with said beam, adjustable arm supports mounted on said beam and in proximity to said controlling mechanism, a skid mounted in the under side of said beam and forward of said propelling means.

- 3. A swimming device comprising an admain beam and positioned in proximity to said controlling mechanism and adapted to L'GCGIYG the arms of a swimmer whereby said sw mmer may operate said controlling mechanism.

In testimony whereof he has afiixcd his 15 signature.
